Definition: Yarn Diet

"Yarn Diet: An approach to yarn control known to be ineffective in dropping permanent pounds from the stash. It can lead to dangerous wool bingeing and yo-yo dieting, wherein the knitter holds off on purchases, shrinks the stash, then rebounds to old yarn habits, gains back the merino, and adds nine balls of the silk. Not pretty to watch."
